| | Diethyl fumarate Usage And Synthesis |
| Chemical Properties | colourless liquid | | Uses | It is used as a pesticide or comonomer
for the production of polystyrene. | | Uses | Diethyl Fumarate is a reagent in the preparation of chiral hydroisoindolines via Diels-Alder cycloaddition which are potent, brain-penetrant, human neurokinin-1 receptor antagonists. | | Uses | Diethyl fumarate is unsaturated polyester resins are used in applications, such as reinforced glass fiber for boats, piping, bathtubs, roof panels, etc., and as protective coatings, finishes, and lacquers. | | Production Methods | Diethyl fumarate is manufactured via esterification of ethanol
with fumaric acid. | | Definition | ChEBI: A dieter obtained by the formal condensation of fumaric acid with ethanol. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 52, p. 323, 1987 DOI: 10.1021/jo00378a045
Tetrahedron Letters, 28, p. 6649, 1987 DOI: 10.1016/S0040-4039(00)96936-3 | | Purification Methods | Wash the fumarate with aqueous 5% Na2CO3, then with saturated CaCl2 solution, dry with CaCl2 and distil it. [Beilstein 2 IV 2207.] |
